I just purchased a 2001 honda passport and when I try to engage the pushbutton on the 4 wheel drive I get a blinking "4 wheel drive" light on the dash. The previous owner says that this is normal when the car is not on a slippery enough surface to remind you to disengage it. Is this sound right? I don't believe him because the 4 wheel drive does not seem to engage but, of course I do not have a manual to answer this question. Can a guy get some help here?!!!!
